Sn Temelli Sn-Pb-Al Üçlü Alaşımında Yapısal, Elektriksel, Termal, Mekaniksel Özellikler ve Mikrosertlik

Öz

Ötektik Sn-Pb-Al (Sn_61.82Pb_38.10Al_0.08) üçlü alaşımı ve sabit Al konsantrasyonunda Sn-Pb-Al üçlü alaşımının (Sn-[x] wt. % Pb-10 wt. % Al) (x=40, 30, 20 and 10) beş farklı örneğinin yapısal, elektriksel, termal, mekaniksel özelliği ve mikrosertliği araştırıldı. Örneklerin sıcaklığa bağlı olarak elektriksel iletkenliği dört nokta elektriksel iletkenlik tekniği kullanılarak ölçüldü. Örneklerin sıcaklığa bağlı olarak termal iletkenliği elektriksel ölçümlerden elde edilen datalarla birlikte Wiedemann-Franz (W-F) yasasıyla gösterildi. Taramalı elektron mikroskobu(SEM), X ışınları difraktometresi(XRD), EDX ölçümleri, yüzey morfolojisini açığa çıkartmak, kristal yapı, hücre parametreleri, tane boyutları ve kimyasal bileşimini belirlemek için gerçekleştirildi. Çekme testleri alaşımdaki her bir bileşimin tane boyutlarına bağlı olarak en büyük gerilme mukavemetini belirlemek için gerçekleştirildi. Alaşımın herbir bileşimi için mikrosertlik sonuçları Vickers test cihazı kullanılarak bulundu.

Abstract

The structural, electrical, thermal, mechanical properties and micro-hardness of five different samples of Sn-Pb-Al ternary alloys (Sn-[x] wt. % Pb-10 wt. % Al) (x=40, 30, 20 and 10) with constant Al concentrations, and the eutectic Sn-Pb-Al (Sn_61.82Pb_38.10Al_0.08) ternary alloy were investigated. The electrical conductivity of the samples, depending on temperature, was measured using the four-point probe technique (4PPT). The temperature dependence of the thermal conductivities of the samples was shown using the Wiedemann-Franz (W-F) law with the data obtained from electrical measurements. Scanning Electron Microscope (SEM), X-ray diffraction (XRD), and Energy Dispersive X-ray Analysis (EDX) measurements were carried out to reveal the surface morphology, crystal structure, cell parameters, grain sizes, and chemical compositions. Tensile tests were carried out to determine the ultimate tensile strengths depending on the particle size of each component in the alloys. The results of the micro-hardness tests were found using a Vickers test machine for each component of the alloys.
